With a SSH remote terminal, I've installed hostmode-gui with the i2c-tools dependency, and appears the big warning. Nothing happens and installation doesn't end...

After an hour (I thought it was frozen) I've taken the device, and seen the license message on screen. Oh, that was the issue!

fcam-drivers package makes the same (graphic message on device screen), but explains it on terminal:
Could i2c-tools package install with the same verbosity?
